IPC: G21K1/093
Filed: 1993-03-15
Abstract: PURPOSE:To provide a simple structural undulator for emitting radiation light by deflecting electron beams in a short cycle. CONSTITUTION:Magnetic fields B1 and B2 having the same magnetic flux direction and located perpendicular to the traveling direction of electron beams are generated at the locations, d apart from each other, by positioning a magnet 1 and a magnet 2 in parallel. Under this state, an electron e<-> enters the first magnetic field B1 at an incident angle of theta to deflect the electron e<-> by (180-theta) deg. degrees at this point. The deflected electron e enters the second magnetic field B2 to the deflect the electron e<-> by (180+2theta) deg. degrees at this point. The electron e<-> again enters the first magnetic field B1 at an angle of theta. Repeating this process forms an electron movement locus as shown in the diagram to reduce a wave pitch (cyclic length) lambdaw. Small size and simplified structure are available due to the low number of used magnets. theta is freely changed. Thus, advantages such as variable lambdaw are available.
